Ephesians 2:1-5 KJV
1) And you hath he quickened, who were dead in trespasses and sins;
2) Wherein in time past ye walked according to the course of this world, according to the prince of the power of the air, the spirit that now worketh in the children of disobedience:
3) Among whom also we all had our conversation in times past in the lusts of our flesh, fulfilling the desires of the flesh and of the mind; and were by nature the children of wrath, even as others.
4) But God, who is rich in mercy, for his great love wherewith he loved us,
5) Even when we were dead in sins, hath quickened us together with Christ, (by grace ye are saved;)
1 Samuel 28:11-15 KJV
11) Then said the woman, Whom shall I bring up unto thee? And he said, Bring me up Samuel.
12) And when the woman saw Samuel, she cried with a loud voice: and the woman spake to Saul, saying, Why hast thou deceived me? for thou art Saul.
13) And the king said unto her, Be not afraid: for what sawest thou? And the woman said unto Saul, I saw gods ascending out of the earth.
14) And he said unto her, What form is he of? And she said, An old man cometh up; and he is covered with a mantle. And Saul perceived that it was Samuel, and he stooped with his face to the ground, and bowed himself.
15) And Samuel said to Saul, Why hast thou disquieted me, to bring me up? And Saul answered, I am sore distressed; for the Philistines make war against me, and God is departed from me, and answereth me no more, neither by prophets, nor by dreams: therefore I have called thee, that thou mayest make known unto me what I shall do.
Revelation 20:11-15 KJV
11) And I saw a great white throne, and him that sat on it, from whose face the earth and the heaven fled away; and there was found no place for them.
12) And I saw the dead, small and great, stand before God; and the books were opened: and another book was opened, which is the book of life: and the dead were judged out of those things which were written in the books, according to their works.
13) And the sea gave up the dead which were in it; and death and hell delivered up the dead which were in them: and they were judged every man according to their works.
14) And death and hell were cast into the lake of fire. This is the second death.
15) And whosoever was not found written in the book of life was cast into the lake of fire.
Much love!
